Khayyal, M. T., H. Roushdy, S. Saleh, M. El-Ghazaly, S. Kenawy, and M. A. el Mazar, "Radiation exposure and the effect of piroxicam and diclofenac on mediator release from isolated guinea-pig lung.", Archives internationales de pharmacodynamie et de thérapie, vol. 298, pp. 247-63, 1989 Mar-Apr. Abstract

The effects of radiation exposure and drug treatment on the immediate type of hypersensitivity reaction were studied. Guinea-pigs were sensitized by s.c. injections of antigen. The animals were killed 3 weeks later and the lungs were perfused through the pulmonary artery. The perfusate was allowed to superfuse a guinea-pig ileum to estimate its total content of mediators. Results revealed that the mere injection of antigen to the perfused lung resulted in the release of spasmogens which caused contraction of the guinea-pig ileum. Analysis of the effluent showed an increase in the amount of PGs (measured biologically) and histamine (measured fluorimetrically) released during challenge. The response of the ileum to the antigen challenge was inhibited by the infusion of diclofenac (20 micrograms.ml-1) or piroxicam (25 micrograms.ml-1). The drugs also inhibited the release of PGs and histamine from the perfused lungs. Exposure of animals to gamma-radiation, before sensitization, caused a reduction in the amount of mediators released during challenge. On the other hand, in nonsensitized animals, a single radiation dose level of 2 Gy caused fluctuation in the amount of PGs and histamine released during challenge throughout the 3 weeks period of the experiment. Diclofenac and piroxicam effectively reduced the amount of mediators released from sensitized perfused lung isolated from both nonirradiated and irradiated animals. This may, at least partly, explain their protective effect against the exaggerated inflammatory response following gamma-irradiation exposure.

el-Baghdady, Y. R., E. S. Fattouh, K. I. el-Ekhnawy, M. M. Ayoub, and L. H. Bedeir, "Role of oxytocin and/or PGF2 alpha on breeding efficiency in buffaloes.", The British veterinary journal, vol. 146, issue 6, pp. 577-81, 1990. Abstract

A study was conducted on 40 buffalo-cows, assigned randomly, immediately after calving into three groups: group I (n = 10) injected with saline and taken as control; group II (n = 15) received 25 mg PGF2 alpha/animal (Lutalyse); group III (n = 15) received 25 mg PGF2 alpha + 25 i.u. oxytocin/animal (Syntocinon), single i.m. dose. Oxytocin and/or PGF2 alpha significantly (P less than 0.01) shortened the interval from calving to first service (38.33 and 31.53 days for groups II and III respectively, versus 91.60 days for controls). The treatment reduced the service period (38.29 and 35.87 days for groups II and III respectively, versus 45.40 days for controls). Concomitantly a significant (P less than 0.01) decrease in the open-days post partum was achieved (76.62 and 67.40 days for groups II and III respectively, versus 137.00 days for controls). In addition, the treated buffaloes needed significantly (P less than 0.01) fewer services per conception (1.67 and 1.20 S/C for groups II and III respectively) than the untreated ones (2.70 S/C), besides a substantial improvement (P less than 0.01) in their conception rate either at 60 or 85 days post partum. Significantly improved (P less than 0.05) results were obtained in the oxytocin and PGF2 alpha treated animals, than in those receiving PGF2 alpha alone for all the previous parameters, except for the service period. Buffaloes therefore seemed to respond better to such treatment than dairy cows.
